Description
Technical Field
[0001] The utility model relates to the technical field of annealing furnaces, in particular to a rapid annealing furnace heating furnace body device. Background Art
[0002] Annealing furnace is a kind of heat treatment equipment commonly used in industrial production, mainly used to adjust the crystal structure and properties of metal materials. The working principle of annealing furnace mainly includes three steps: heating, insulation and cooling. The temperature in the furnace is raised to the required annealing temperature through internal electric heaters or gas stoves and other heating equipment; when the temperature in the furnace reaches the required annealing temperature, the metal material will be kept at this temperature for a period of time, and this process is called insulation; after the insulation is completed, the annealing furnace will gradually reduce the temperature in the furnace by controlling the gas supply or turning off the heating equipment.
[0003] After searching, the patent with application number 202111595920.9 discloses an infrared rapid annealing furnace, including a furnace body, which is provided with upper and lower rows of infrared lamps, and infrared heat insulation baffles are provided between adjacent infrared lamps to block the transmission of infrared light. This invention separates adjacent infrared lamps by using infrared heat insulation baffles. The infrared heat insulation baffles are resistant to high temperatures and are not conducive to the transmission of infrared light, thereby weakening the heat radiated from the edge lamps to the center position, isolating a single infrared lamp as a separate radiation heat source, greatly reducing the transmission of infrared waves, and can effectively alleviate the edge field effect during the heating process of the silicon wafer, and maintain the silicon wafer with good temperature uniformity.
[0004] The temperature measurement inside the furnace body of the current rapid annealing furnace for metal heat treatment is not accurate enough. Too high or too low temperature is not conducive to the quality control of product heat treatment, and high temperature easily causes energy waste. In addition, the current rapid annealing furnace is more troublesome to open and close the furnace door during metal heat treatment, which is inconvenient for metal loading and unloading, thereby reducing the metal heat treatment efficiency. Therefore, we need to propose a rapid annealing furnace heating furnace body device. Utility Model Content

[0022] As a temperature measuring element, the temperature measuring thermocouple 17 can generate an electromotive force by using the temperature difference at the contact point of two different metal conductors, and then accurately measure the high temperature in the furnace. By monitoring the temperature changes in the furnace in real time, the temperature measuring thermocouple provides a feedback signal to the furnace temperature control system. This helps to control the operation of the heating equipment, thereby ensuring the stability of the temperature in the furnace and the safety of the heating process.

[0024] Both ends of the furnace door 8 are connected to connecting rods 81, and the locking mechanism includes two positioning rods 9 rotatably installed at both ends of the furnace door 8, and a door opening handle 10 is rotatably connected between the two positioning rods 9. The positioning rods 9 are set as Z-shaped positioning rods, and the ends of the connecting rods 81 are rotatably installed on the positioning rods 9.

A clamping groove 91 is formed at one end of the positioning rod 9 . The clamping block 111 is clamped in the inside of the clamping groove 91 .
